FAQ:

1: Are you a Ball Screw manufacturer or a trading company?

We are a manufacturer which hasmore than20 years' history.

2: Where is your manufacturer? How to visit it?

Our factory located inYutian Economic Development Zone ,TangShan ,China.about 1.5 hours drive time to Beijing and TianJin airport .Mainly producing pre-insulated pipes,HDPE outer protection pipe and 3PE anti-corrosive pipe.

You can take a plane to Beijing or Tianjin.then we could pick up you at the airport .

3: How do we control our products' quality?

We have professional quality control workers and quality inspectioncenter(CNAS lab)to control the entireproduction quality.

4: How do you transport these products?

We use straps to hoist pre-insulated pipes, it can avoid no damage to our products, no hooks for lifting pipedirectly. During the handling process, collision, tossing and more ground drag scrolling are strictly forbidden.

In the process of long distance transport, the pipes should be fixed, and not damage outer protecting pipesand insulating layers.

5: Can I customize some other sizes of products?

Yes! We can according to the customer's request.
If you have any other questions, please don't hesitate, contact us.6:Can we get a sample? how topay?
Small size,the sample is free,and you just pay for the freight.
